Page 40: 4　Startup
Startup 4 Startup To startup BX6.3_AC100, please follow the steps below: 1. Turn ON the AC grid breaker. 2. Ensure the LED light-on, follow the "MyDeltaSolar"APP user's guide to operate the APP. 3. When DC1 is also in the system, please ensure the connection between DC1 and BX6.3_AC100 and check if DC1 is powered correctly.
Page 41: Operation Mode
Startup 4.1 Operation Mode BX6.3_AC100 has 6 normal operation modes for users to choose. Each mode has different behavior between battery, grid, and home load. The following are the description of these modes. In some area, the detail behavior of each operation mode may be different due to the local electricity regulations.
Page 42: Peak Cut Mode
Startup 4.1.2 Peak cut mode In this mode, the home load will consume the power from the PV inverter in priority. When the home load consume more power than the power generated by the inverter, it will consume the power from the grid. Then, battery will only discharged to the supply the extra load after the power consume from the grid exceeds the “peak cut power”...
Page 43: Selling First Mode
Startup 4.1.3 Selling first mode Selling first mode is a standard mode combining with 6 time settings. In this mode, BX6.3_AC100 is operated in following priority: 1. If users have set the time settings, inverter will change behavior in these time intervals 2.
Page 44: Charge First Mode
Startup 4.1.4 Charge first mode In this mode, battery will be charged by PV or grid in priority, after battery is fully charged, the remaining PV power then feed-in to home load and grid. Battery will not be discharged in this mode even there is demand in the home load. Feed-in / purchase Distribution Panel Solar Panel...

Page 46 Startup 4.1.5 Discharge first mode In this mode, the battery will only be discharged depends on the load consumption. It will not be charged even there is excess PV power. All the PV power is feed-in to home load and grid. Battery will keep discharging when there is demand in the home load until it fully discharged.
Page 47 Startup 4.1.6 Special Modes In addition to the modes mentioned above, there are three special modes in BX6.3_AC100. These are passive modes, they will be enabled automatically under special condition. • Standalone mode BX6.3_AC100 changes to standalone mode automatically during a power outage occur.
Page 48 Startup • Forced charge mode Although battery stops any action when SOC (state of charge) reach 0%, the self-discharge phenomenon may still causing SOC lower than 0%. At this time, BX6.3_AC100 will force battery charging from PV power and grid power until the battery SOC reaching SOC limit setting (default is 30%).
Page 49 Startup • Balance mode This operation is only applied to BX12.6_AC100 system. During the installation, the battery voltage of BX6.3 series might be different. Due to the specifications of the battery module, the system will be switched to this mode automatically to balance the voltage of BX6.3 series. When the system is operating under this mode, the system will either discharge the battery with 3 kw power to the load and the grid or charge the battery with 3 kW power from the grid.
Page 50 Startup 4.2 Function Setting You can assign SOC limit, peak cut power, BT charge / discharge time interval, Main Supply Breaker Capacity and Time Schedule for SOH-cycle. • SOC Limit You can assign the lower limit of battery SOC. Battery will stop discharging when its SOC reach this limit.

V_max upper limit i limit s limit lower limit V_min Curve A 4.3.2 P(U) control When grid voltage rises up to a lock-in voltage(V lock-in) and inverter’s present output power is greater than lock-in power(P lock-in), inverter will reduce the output power and keep it at a certain value(P lock-out) until grid voltage drop...
Page 52 System application 5 System application ATTENTION - Short circuit at the critical load may cause damage to the inverter. 1. Critical Load Backup Power This system can provide power to the critical load once there is a power failure. The maximum power consumption for the critical load is 3 kVA for BX6.3_AC100 and 4.5 kVA for BX12.6_AC100.
Page 53 System application 2. Hybrid Energy Storage System This system is a combination of PV inverter and BX6.3_AC100, it can be considered as a hybrid energy storage system. In this system, BX6.3_AC100 can store the excess PV energy during daytime and provide energy to the load when there is load demand. This system can support multiple HxA PV inverters depends on the customer requirement.
Page 54 System application 3. Off-Grid Support Hybrid Energy Storage System (Internal ATS Mode) The key feature of this system is that it can support off-grid application and the PV inverter can continue generating power during power failure. In this application, the auto contactor is not necessary as it applies the internal contactor of BX6.3_AC100.
Page 55 System application 4. Off-Grid Support Hybrid Energy Storage System (External ATS Mode) This system is similar to application 3, it can support off-grid application and the PV inverter can continue generating power during power failure. However, a time-delay external auto contactor is required in this system. The time-delay auto contactor will trip off immediately when power failure and closed after the grid is recovered for 3 seconds.
Page 56 System application 5. Backup Power with Higher Standalone Power This system can provide higher output power to the critical load once there is a power failure. To achieve a higher standalone power, the SPS port of multiple BX6.3_AC100 should be connected together. The output power during power failure will depend on the number of BX6.3_AC100 connected.
